1 is a schematic block diagram of the brushless motor relating to the present invention. A motor body 1 has a well-known structure that a magnet (not shown in the drawing) is attached to a rotor (not shown in the drawing) installed so as to rotate and a plurality of drive coils 1a,...
Electricity enters the motor via the brushes (shown as graphite brush in the schematic). These brushes touch the commutator, which receives the electrical current and passes the voltage through copper wiring to the internal coils. The electromagnetic force pushes the core away from the North polarit...
